Specifications

the advantage of mechanical strength,
excellent stability of thermal shocking,
resistance to corrosion of glass liquid.

Dense Zircon brick mainly used in upper area of flame space or frequent thermal shock region of alkali-free or low-alkali glass, sodium-calcium glass, boron-silicate glass, lead glass and other technical glass melting furnace, such as transition region between up roof silica brick and fusion zirconia-corundum brick or fusion zirconia-mullite brick, transition region between silica brick and magnesia brick, crown, burner, thermal couple, peep hole, secondary layer of melting bottom and its back its back lining, and also used in ladle lining for metallurgical industry.
